问题描述
我有很多对象要保存在数据库中,所以我想用它创建模型实例.
I have a lot of objects to save in database, and so I want to create Model instances with that.
使用 django,我可以创建所有模型实例,使用 MyModel(data)
,然后我想将它们全部保存.
With django, I can create all the models instances, with MyModel(data)
, and then I want to save them all.
目前,我有这样的事情:
Currently, I have something like that:
for item in items:
object = MyModel(name=item.name)
object.save()
我想知道是否可以直接保存对象列表,例如:
I'm wondering if I can save a list of objects directly, eg:
objects = []
for item in items:
objects.append(MyModel(name=item.name))
objects.save_all()
如何在一笔交易中保存所有对象?
How to save all the objects in one transaction?
推荐答案
截至 django 开发,存在 bulk_create
作为对象管理器方法,它将使用类构造函数创建的对象数组作为输入.查看 Django 文档
as of the django development, there exists bulk_create
as an object manager method which takes as input an array of objects created using the class constructor. check out django docs
